How is your 2GB iPhone 6s faster than my 4GB LG G5?!

This is an expansion/continuation on my first blog post, and I will be referring to terms already explained previously. So if you haven’t read that one yet, you might not understand this post as much as you should, so please go read it!

Done? Then here we go!

Now that you’re familiar with what components we as consumers should know, it’s time for me to take all those knowledge throw them away. Unfortunately, in the real world, higher specs does NOT always mean better performance. This is especially the case for smartphones. Don’t believe in me? Take a look at this video first.

The video compared 4 of the most recent phones in 2015/16 from 4 different companies. The iPhone 6s Plus by Apple, the Galaxy S7 Edge by Samsung, the Moto X Pure Edition by Motorola, and the Nexus 6P by Huawei. I’ve linked the their individual specs from the website GSMArena (a fantastic site if you want to know more about smartphones) so that you can compare with me. Scroll down to the platform and memory sections and see for yourself.

With what you were informed before (higher number is better), it would be logical to assume that Galaxy S7, with 16.8 Ghz total for CPU and 4GB of RAM, should be the fastest phone. The other phones should be much slower than the S7. But the iPhone, with the lowest CPU clock speed (3.68Ghz) and RAM (2GB), was the fastest by a long shot! The S7 only came second after nearly 18 seconds, immediately followed by the 6P, then the Moto X came last. How is this even possible? The S7 on paper should excel at doing so and trump the 6S.

This is due to something call optimisation. Apple is responsible for designing the components and the software of the iPhone, so they are familiar with what they’re dealing with. This give the iPhone a huge advantage of using all of the available resources it has. On the other hand, Samsung is responsible for neither the hardware nor the software of the phone. The S7 runs Android made by Google while they use CPU (Snapdragon 820) made by the company Qualcomm. Imagine two people with limited food sources, the one that knows how to ration the foods daily will still be able to survive longer than the one that doesn’t even if he/she has more food.

The reason I’m saying this, as a continuation of the previous post, is to make a point that things might often not be what they seem like. This is very much like science, correlation does not necessarily mean causation. An example might be that animals with bigger brains are generally more intelligent, a nice counter argument would be humans compared to elephants! Our preconceptions on things might lead to faulty science!

Until next time!

Self-Driving Cars: The future of transportation?

Vehicles, trains, ferries, planes – just examples of the wide range of transportation methods available in the modern day.  All of these methods require a human operator, however, we are soon to be introduced to a method seldom heard of: self-driving cars.  In 2009, Google launched the Self-Driving Car Project and began development of a vehicle that drives itself from point A to point B without the need of a driver.

An operating software works alongside the sensor seen visibly on top of the vehicle. The sensor consists of lasers and cameras, and it is able to differentiate surrounding objects by a combination of size, speed and shape. With this information, the software is able to anticipate what happens next (for example, if a cyclist passes by).  In the current prototype, the car has no pedals nor steering wheel – the only way humans can control the driving is a red button for emergencies. Google’s prototypes have been released in California and are expected to be released to the public by 2020.

Other examples of  self-driving vehicles include Tesla models, which have been on the roads of Canada.  Compared to Google’s project, Tesla’s models are not entirely automatic, as they still require a driver to command lane changes and they require a driver to be present and touching the steering wheel periodically.  Nonetheless,  it still contains functions such as cruise control, automatic parking,

hand-free lane changes, and top speed limit.

Apart from not needing a driver, what else does a self-driving car offer?  Google’s prototype is environmentally friendly because it is completely battery powered. The computer of the vehicle is also programmed to drive safely, although Google has the ability to set the aggressiveness of the drive.  Consultancy firm KPMC predicts self-driving cars can reduce accidents by 80% and an estimated 2500 fewer deaths due to car accidents between 2014 to 2040.

The self-driving car still has it’s limitations though.   The software in all models are still to be perfected and we are still seeing accidents in prototypes. Questions have also been raised about common driving circumstances,  such us backing up a few feet for convenience, or deciding if someone should be let into your lane. If every car on the road was programmed, perhaps we could little to no car accidents.  However both the hardware and software is fairly expensive, such as Tesla’s software requiring a $3000 add on.  In addition there are various legal issues. Ontario still requires a driver  to be in the driver’s seat at all times. Responsibility of accidents are still to be decided between the user and manufacture.

With many factors still unknown, the popularity of the self-driving car in the future is still debatable. However, we can continue to expect steps in development and new self-driving models to appear.
